ESP8266-based touchscreen clock and light controller with WiFi

ESP Clock

Touchscreen clock and light controller with WiFi

This was a week-long hack, to build a simple touchscreen clock, with the following features:

• Graphical UI with touch (no buttons)
• Clock synchronization over NTP
• Ability to control WiFi-connected LED lamps
• Web-based configuration UI

This project was partly inspired by the Chumby (remember that?) and by our old X10 light controller (remember those!?). Current iteration's cost is probably comparable to a used Chumby (which also has a lot more features), but it's more fun this way. :) However, the cost could be taken down to ~$10.

Dependencies

• My rewrite of the Digole library
• ArduinoJson
• Time
• Arduino ESP built-in libraries (WiFi, WebServer)

Also, for flashing fonts, you will need the original DigoleSerial library (haven't tested/ported the font upload stuff in my rewrite) and, if you want to substitute your own fonts, the font conversion tools from u8glib/ucglib.

BOM

• Sparkfun Thing
• Digole 2.4" IPS display (in UART mode, with wire soldered to reset pad)
• 500mAh LiPo (optional, but recommended)
• Depending how fancy you want to get with print finishing: XTC-3D resin and/or Bondo putty, spray paint and primer

More details can be found in the making-of post.

espclock's Issues

Move static HTML to SPIFFS

Use SPIFFS for static content; put CSS and JS into separate files.

Weather info display

Update UI screen to display current weather conditions.

AJAX for light control over web.

Write HTML for light control web UI; API endpoints already there (untested).

Fix minified HTML

Minifier (css-html-js-minify.py) does not really support HTML with embedded JS; current minified settings.html is broken.

Improve initial setup

Sort out the AP->AP+STA->STA transitions and make initial setup work more smoothly.

Currently, it's either AP or STA, until reboot. Disconnecting from the soft-AP got the station i/f to hang?

On/off timers

Add lamp on/off timers, possibly emulating old X10 button interface: repeatedly tapping "On" increments an off timer interval; for on timers, configure presets via web UI, and cycle through them by repeatedly tapping "Off".
